Spain preview quotes: Sauber

The circuit has become the best test track for Formula 1. It is a very demanding circuit - tough on the cars, the engines and the drivers. It is a track I really, really like. Turn three is very fast and very long - it is a true neck killer. There is a great variety of corners - high and medium speed, and a couple of slow ones in the last sector. We had a good winter test there and I have the feeling our car suits Barcelona better than some of the more recent tracks. For the Spanish Grand Prix we will also have a new aero package in place. I'm sure at the end of the race we will either be close to or in the points."

Kamui Kobayashi: "I know the Circuit de Catalunya pretty well. I won a GP2 race there, raced there in Formula 3 and did some Formula 1 testing there. Even my first ever F1 test was in Barcelona. In those days the last two corners were different to now, as it was a very fast double right hander. The circuit is very demanding on the cars and challenging for us drivers. The car-and-driver combination has to be very good, as it is difficult but crucial to get the set-up right. The fast right hander before the back straight is my favourite corner and quite challenging.

"I like Spain and the Spanish Grand Prix. The weather is usually very nice and there is a large crowd. I'm happy for Pedro that it is his home race and all his fans will be there. We have been testing there over the winter. We have an update to the car and I believe our reliability problems are solved. I should have a good chance to finally go racing after I have only done 19 laps in total in all four races."

Technical Director James Key: "We have some updates for Barcelona, as most of the teams will have. We are trying to push our F-Duct design a step further. This is obviously a technology that will eventually appear all the way down the grid during the year, but our team has some experience of it from the first events.

"Additionally we have a package of updates on the car, which are particularly on the front end and the diffuser. It's a decent package, which will hopefully allow us to find some more performance. Obviously a lot depends on how tough the competition is. Some of the steps address the issues the team has identified in terms of the aero characteristics, so it should make the car a little bit better purely through changing the way it behaves.

"With regard to the circuit itself, it's obviously a place everybody knows extremely well. It's an excellent reference circuit with a real mix of low and high speed corners, which require downforce as well as a good mechanical grip. It's a very technical circuit where it's never been easy to get the best out of the car. It will be interesting going back there after the cars have developed since winter testing, and to see how much they have changed. An important question will be how well we can get the tyres to last because it is a very hard circuit on tyres; and, of course, the difference in temperature between winter and now is also an interesting aspect. "I'm looking forward to the event. It's obviously Pedro's home race, which is great for him and, as a team, we will try to have a good weekend and put the difficult start to the season behind us."
